Honestly, I think people are underestimating the Raiders. I know I'm surprised by how much they progressed, especially Pryor. Are they an overally good team? Not quite, but they are making strides, starting with Pryor. They aren't turning the ball over, and playing decent enough defense at times. Heck they almost knocked off the Colts in Indy to start the year.
Add to the fact it is a divisional game, rivalry, I think it is a close game.
